Exploring Gaps in Child Maltreatment Trends: A Narrative Review from the U.S. and Japan.

Child maltreatment affects millions globally across all economic levels. Despite its prevalence, comparative research and internationally comparable data are limited due to varied definitions, methodologies, and reporting systems. This narrative review aims to compare child maltreatment trends in the U.S. and Japan, highlighting the roles of sociocultural factors. Through a literature review and analysis of national data since 1990, the study estimates maltreatment and fatality rates in both countries. Findings suggest an increase in Japan's reported maltreatment cases, likely attributable to legislative changes and heightened public awareness, while the U.S. appears to show a decline, potentially linked to improved mental health services and socioeconomic advancements. In both nations, mothers are predominantly identified as perpetrators, with sociocultural factors influencing maltreatment types and rates. Japan faces challenges in accurately measuring maltreatment due to reporting inconsistencies and mental health stigma. Despite a higher victimization rate, Japan reports significantly fewer fatalities than the U.S., with the fatality rate in the U.S. being approximately 9 times higher than in Japan. This contrast underscores the critical role of healthcare access and mental health support. The review advocates for international efforts to standardize maltreatment definitions and reporting, suggesting the adoption of trauma-informed care and comprehensive healthcare access as effective strategies.
